I have a non prof. interest in non linear dynamics, plasma, the very massive and not massive at all.

Also interested in number theory and set theory.

Just looking for folk to chat to, you're an interesting bunch...

Possibly

The overall result qt the time was a faint green glow in the bubble. I was in a total dark room.

I think at the time I did manage it.. but as the time passes I doubt whether I did or whether it was hope rather than reality. I did promise to buy the equipment needed and arrange a set up at home.. maybe once the kids are self sufficient I will.

It was also based on energy spikes, set frequencies.. boosting the power of the system with a potential divider.

I do recall being happy producing degassed water - which is much easier than you think. Such simple things made me happy back then.

If you had a glow it was coming from somewhere! I'd say you did it.

Since I became a full time carer I've started building valve amps, for fun. I play guitar and bass so it's a natural progression really. It's keeps my mind occupied and brings me pleasure.

They're all over Lorenz attractors

I'm struggling with point gravity as used by einstein in his field equations. It seems that every massive particle would have an attraction for every other interacting particle. I need help arriving at a formulation of navier Stokes and nash's game theory to replace point gravity which describes the motion of perturbed fluids on the basis of their gravitational attraction only. I'm dyslexic I can't do the algebra but I can see the picture.

I find the quantum stuff really interesting precisely because of that crazy stuff. I understand some of it, like quantum tunneling. The double slit experiment and entanglement are a real challenge, sometimes I think I have it bit I really don't. I'm trying to get to grips with the standard model atm.

Gravity waves are pretty interesting at the moment I think. I find the concept pretty amazing.

I did read an article a while ago about superfluids in neutron stars and how heavier elements could crystallise out of them. I'm not sure how that corresponds with the gravity wave data. Certainly mass is lost in neutron star collisions, I thought the prevailing view was that it was converted to energy. I'll look up kilonovas. Thanks

Correct. I have a decent grasp of the concepts which gives people in my position the title of Quantum Storyteller. A basic understanding of the principles but not from a mathematical point of view. Concept understanding will only get me so far. And if the forefathers of quantum mechanics say it's a mess what chance have I got

It's a tricky one. Einstein founded quantum physics. His teachers at University thought he was a twit. His family had to assist him in finding a job. He wrote his first paper as a patent clerk which was generally overlooked. He clearly struggled with the maths and conducted thought experiments of the principles which he would later formalise into general relativity using Riemann tensor matrices. QM none really understands at the moment but the maths seems to work OK up to a point! Most are familiar with to shrodinger's cat, hiwever Heisenberg's uncertainty principle is far more revealing imo.

An area I'm particularly interested in is non linear dynamics. Chaos basically. To mathematically describe and predict chaos or nonlinear transitions between alternate states is impossible at the moment. However we can all recognise fractal patterns. Emergent phenomena are familiar beautiful and commonplace. The basic concept underpinning evolution is disarmingly simple and yet it evaded detection until Darwin and Wallace glanced in that direction.

Did you know, all the gold on earth was formed in a split second during the formation of the earth, at billions of degree's C.

No new gold has ever or will ever, be formed again.

Not quite. The earth took quite a while to acrete from the remains of some massive astronomical event; gold is formed frequently during these events. I've just been reading about about a neutron star collision in 2017 which is believed to have formed between 3 and 20 earth masses of gold.

Gold has also been produced on earth quite a few times by nuclear physicists. It's extremely unlikely any of that will be found on your finger though.
